' This invention relates to a combination of a tractor and a loading mechanism for loading hay, sheaves or bundles of grain and similar material disposed at and supported from said 'tractor at one side thereof, said loading: mechanlsm comprising an endless carrier which is driven from said tractor. l f

It is often desirable toload hay or grain onto a vehicle andto have the loader move along after the cutting mechanism. It is thus desirable to l have the loading mechanism when driven by a tractor at one` side ofthe tractor so that the loading mechanism can move alongnext to the standing crop without either the loading mecharunningover the same.` It

have the loading mechanism` s (ci. 19a-n) panying drawings in which like referencechar` acters refer to similar Aparts throughout the several views and in w cli--` Fig. `1 is a view in side elevation of the tractor and loading mechanism supported thereby, some parts of the loading mechanism beingshown in diiferent positions in dotted lines;

. tractors could be used. in the embodiment of the disposed at one side of the 'tractor for the con` `venience of operation and so that the vehicle to be loadedmay be conveniently disposed and drawn. It is also objectionable to have the loader longitudinally alined with and extending directly over the tractor.

It is an objectof `this invention, therefore, to provide simple and emcient means by `means of m which the loading mechanism may bei4 disposed at one side of, supported from and driven'from said tractor. j v

It is a further object of the invention to provide" simple. and eiiicient/means which may be connectedto the tractor frame adjacent the front and rear thereof and which carries supporting members for the loading mechanism.

said 'loading mechanism being disposed at one side of the tractor the regular pulley so that it can be driven from shaft of' said tractor.

Referring to the drawings,` a tractor is illustrated and while various formsof commercial afront axle on which are disposed the front wheels I 0e, member "d being rotatable about a vertical axis.` 'I'he tractor is provided with the usual operators seat 'llf and steering wheel ilig and has'a pulley shaft ih. at one sidecarrying It is more specifically an object of thefinvention to provide means for tractor comprising a secured to one end of said member, a second ver-` tical standard secured to the tractor frame at the rear portion thereof, said loading mechanism having one `of its side members connected to and supported by said vertical members, l members preferably being provided extending from adja `cent the top of said vertical member to the opposite side" of said first mentioned member and Mtractor frame respectively, together with means for operating said loading mechanism fromsaid tractor.

These and other invention will be fully set forth in the following supporting a loading t objects and advantages of the `a lpulley lli which is sometimes n illustrated the same is used for driving other `machines or mechanisms. Frame portion Illa has at either side thereof lugs |07 having"l vertically spaced horizontally extending holes therethrough. m The loading mechanism might take different forms, but inthe embodiment ofr the invention shown as comprising upy wardly and rearwardly ei'rtending side frame members Ila between which is supported and moves an endless carrier I2. Endless carrier I2 comprises a flexible member or apron i3`having suitable spaced cleats or bars I4 secured thereto. Member il runs over rollers I5 and i6 disposed respectively adjacent the top rear end and the lower front end of said loading mechanism. Roller I5 is supported upon a revoluble shaft "l'l journaled in bearings carried in the side frame members ila and roller I6v is carried on a.

revolublev shaft Il` supported in suitable bearingsl carried in bars I! respectively which are lsecured to the outer sides of the side frame members ila. `In accordance with the present invention vertically extending bars 24 are secured tothe spaced description madein connection withthe aceomrlugs N1 4by headed and nutted bolts 25 extending A standards 4| and 45 and at their other ends so that their top surfaces lie in a horizontal plane. A horizontally extending bar 26 -is supported upon and secured to the tops of the bars 24 by headed and nutted bolts 21. Bar 26 extends to either side of the bars 24 and has its end portions 26a bent downwardly at a right angle. A vertical standard 28 is secured to the end of bar 26 at `the pulley side of the tractor. Another bar 30 is secured to the downturned endof bar 26 byfone of the headed and nutted bolts 3| which secure standard 28 to .bar 26 and extends downwardly diagonally to andis secured by the lower bolt 25 securing -the adjacent bar 24. Standard 28 is secured to one side frame member Ila of the loading mechanism and acts as 'a support therefor. A second vertical member 32 is secured to the other side frame member lla transversely alined with standard 28 and said vertical mem- -bers are connected by a rigid bar 33 extending therebetween having its ends downturned and convnected thereto by the headed and nutted bolts 34.

A rod 35 is secured to vertical standard 28 adjacent its upper end and extends downwardly diagonally and has its lower end secured by headed and nutted bolt 36 adjacent the end of bar 26 opposite that to which standard 28 is secured. A bar or rod 31 has one end extending through standard 28 and the upper end of bar 35, said end being threaded and equipped with a nut 38. Rod

31 extends downwardly to and through standard 32 and has its end equipped with a nut 39 disposed at the outer side of standard 32. A vertical standard 4| is secured to one side of rear frame member |01, the same having its lower end bent at a right angle and secured to said member Ib by the bolt 42. Standard 4| extendsv vertically along the side ||a of the loading mechanism and is secured thereto by headed and nutted bolt 43. A bar 44 extends between standard 4| and a similar standard 45 disposed at the opposite side of the loading mechanism and secured to the opposite side frame member at the outer side thereof and transversely ali'ned with standard 4 I Bar 44 is secured at one end by bolt 43 and is secured the outer sides of side members Ila respectively at points rearwardly of said standards. Rods 53a are secured at one end to standards 4| and 45 a short distance below rods 53 and extend downwardly to and are secured to the lower portion of standards 28 and 32.

The loading mechanism illustrated comprises a pick-up swinging front section designated generally as 58, the same comprising longitudinally extending side frame members 58a suitably connected to and carrying bearings 59 in which are disposed shafts 68 and 6| disposed respectively at the lower and upper ends of members 58. Said shafts carry sprockets 62 and 63 adjacent the side members 58 over which run chains 64 and 65. Cross pieces 66 extend between and are secured to chains 64 and 65 and these cross pieces which are in the shape of angle bars have secured thereto transversely spaced teeth 61. The shaft 6| extends through bars 69, which bars are secured at their upper ends by bolts 19 to the outer sides of standards 28 and 32 and are secured at their at its other end to standard by abolt 46. A'

rod 41 is secured to standard 4| adjacent its uP-' per end and extends downwardly to the frame member |0b and is secured thereto by a bolt 48 at the side thereof opposite that to which standard 4| is secured. A rod 56 has lone end extendingthrough standard 4| and rod 41 and threaded to receive a bolt 5|, this rod thus securing the upper end of rod 41 in place and the same extends downwardly to and through the upper end of standard 45 and is equipped with a nut 52 at the outer side of standard 45. It will thus be seen that the loading mechanism has`vertical standards secured to its side frame members adjacent the front and rear portions thereof and the vertical standards adlacent the tractor are firmly secured to and supported by the tractor frame and further braced'and supported by rods 35 and 41. These parts together with bars 33 and 44 and rods 31 and 56 form a strong and rigid support for the loading mechanism. Preferably a bar 54 extends beneath the `loading mechanism and belower ends by bolts 1| to the lower ends of bars I9. Shaft 6| can oscillate in the bars 69 so that the pick-up member 58 can be lifted and oscillated about shaft 6|. Each side member 58a has secured thereto at its outer side a bracket 13 bored to receive a trunnion 14a of a yoke 14 in which is journaled the axle of a caster wheel 15. The trunnion 14a \will be held in bracket 13 by 'some suitable means (not/shown). A bar 13a,

extends beneath and between side members 58a and between brackets 13, being secured to the latter. A link 16 is pivotally connected by a' stud 11 to bracket 13 and is apertured at its other end to receive the end of a flexible cable 18. There is a link 16 and cable 18 at each side of the pickup member 58 and these cables run over sheaves 19 journaledv on suitable studs 86 secured respectively in the standards 28 and 32. One cable 18 at its other end is connected to an arm 82 secured to a shaft 83 journaled in the standards 4I and 45. The other cable, namely the one nearest the tractor, is connected to a hand lever 84 secured to shaft 63. Hand lever 84 has connected thereto a pawl 85, the lower end of which is adapted to engage in one of a plurality of notchesl formed in a ratchet segment 86 secured to standard 4|. A spring handle grip 81 is pivoted to handlever 84 adapted to be gripped and moved to ratchet pawl.85 from its notch so that lever 84 may be oscillated. It will be seen that when lever 84 and arm 82 are oscillated with shaft 83 that cable 18 will be moved and that the pick-up member 58-may be raised or lowered. Shaft 6| has secured thereto at each end a sprocket 90 over which runs a chain 9| also running over a lsprocket 92secured to each end of the shaft I8.

Shaft |8 also carries a sprocket or pulley 93 over which runs a belt or chain 84 also running over and driven by a sprocket or pulley 95 secured to the'pulley shaft 2| of the tractor.

With the described structure it will be seen that the loading mechanismis supported from the tractor by vertical standards 28 and 4|. These standards are secured to the tractor frame as described and are rmly supported by their connections as well as by the brace members 35 and 41. The cross pieces 33 and 44 extending to the standards at the side of the loader opposite the tractor cooperate in making a rigid frame for supporting the loader. The pick-up member 58 when in operative position rolls on the caster wheels 15. In the loading operation the tractor to 75 will be moved yforwardly and chain 94 will be ture by means yoi which driven 'by sprocket ss'andwin rotate shaft la.

f 'I'his will rotate roller i6 and the endless member l i3 will `be moved so that its top flight moves upwardly between the side frame members Ila.

.c Shaft 6| will be rotated `by" chains 9| and chainsV 64 and 65 willbe driven from shaft 8|.

aaearei t 3 bers rigidly secured to said iirst mentioned member, a bar rigidly secured to and supported at the upper ends of said spaced vertical members and extending laterally beyond the sides of said traccarried by members 65 and 66 wardly and `delivered over` the upper rear end of r the endless carrier and will thus be delivered to the vehicle on which they are to be loaded.` The shown at one side-` of the loader is disposed as tractor at the front portion ofthe latter and is disposed over one rear wheel of the tractor at the rear end thereof; The tractor is thus not covered by the loader and the vision Voi'the driver of the tractor is not obscured by the front portion of the loader. 4 The loader can be moved along adjacent standing grain or it canbe' moved along as desired in alinement `with a t terial to be loaded. When the loaderI is being transported from one distance the lever 84 can be swung to lift the pickup deviceto the position shown in dotted lines in Fig. 1. i

From the above description it will be seen that I have provided 'a very simple and eiiicient structhe loader maybe supported from and disposed at-one side of the traciob'to another or for any windrow to pick up theimay said bar and an auxiliary tioned member.
